First, the background. I'm a small business owner who is always out on the road. I currently have a Treo 750 running WM, but I want to switch to the iPhone. I use a laptop running Windows XP (but plan a switch as soon as the new MacBook is out). Now, the question. The Treo allows me to store files and email them as I'm standing in front of someone. Will either of the four options above allow me to email files that I'm storing on the iPhone? Thanks for your help on this.
